Maintenance

The preferred method of maintaining a light unit is to periodically and systematically replace the unit and
return it to the maintenance shop for renovation. As an alternative, the light unit can be serviced in the
field. However, it is recommended that field servicing be limited to cleaning the lens only as described in
section 0. For extensive field service, refer to sections 9 and 10 for instructions and spare parts kits.

Cleaning Lenses

With a compressed air blast or suitable brushes, remove all accumulated debris from the light channel.
Clean the outer surface of the prism with a detergent solution. If the lens is coated with a substance
impervious to the detergent, a suitable solvent should be sparingly applied with a wad of cotton or a patch
of cloth on the end of a wood splint. After the solvent has acted the remaining solvent and softened coating
should be removed with a clean piece of cotton or cloth. Care should be taken to avoid excessive contact
between the solvent and the lens seal. Remove all remaining solvent from lens and seal. A gentle air blast
may be used.
